FIG. 1C is a view illustrating a hardware structure for a processor anda display control modice of an electronic device according to variousembodiments of the present disclosure.

Referring to FIG. 1C, the processor (for example, the processor 120) mayinclude a first processor 121 (for example, application processor (AP))and a second processor 122. The display control modice (for example, thedisplay control module 170) may include a first display control modice171 for controlling a first display 151 and a second display controlmodice 172 for controlling a second display 152. The first displaycontrol modice 171 and the second display control modice 172 may beincluded as parts of the logic performed by the first processor 121 andthe second processor 122, respectively. The first display control modice171 may be connected to the second display control modice 172 of thesecond processor 122 through an internal interface circuit 125 of thefirst processor 121.

According to various embodiments of the present disclosure, the firstdisplay control modice 171 may control information display through thefirst display 151 based on (or in response to) at least one of eventsoccurring from the electronic device 101, for example, the relativeposition between the first display 151 and the second display 152, anopened/closed state of a cover for the body of the electronic device101, information to be displayed on the first display 151, a function orapplication to be executed through the first display 151, information tobe displayed on the second display 152, a function or application to beexecuted through the second display 152, or a user input.

According to various embodiments of the present disclosure, like thefirst display control modice 171, the second display control modice 172may control information display through at least a portion (for example,the transparent display area 153) of the second display 152 based on (orin response to) various events occurring from the electronic device 101.According to an embodiment, the second display control modice 172 mayadjust the transparency of the transparent display area 153 in responseto a specific event. According to an embodiment, the second displaycontrol module 172 may control a screen change of the transparentdisplay area 153 in response to a specific event. The second displaycontrol modice 172 may control the transparent display area 153 so thatat least a partial area of the transparent display area 153 displays anobject (for example, image or text) in an opaque state and the remainingpartial area has a transparent state. According to an embodiment, thesecond display control module 172 may generate an image obtained bycapturing a screen outputted to the transparent display area 153 inresponse to a specific event. The second display control modice 172 maybe implemented in a chip form (for example, the second processor 122)separated from the first display control modice 171 and may then bedisposed at one of the body or cover of the electronic device 101.

According to an embodiment, the second display control modice 172 mayinclude a 3D modice 183, a depth modice 186, an augmented realityprocessing module 189, and/or a visibility processing modice 192.According to an embodiment, when at least a portion of an imagedisplayed on the first display 151 is seen through the transparentdisplay area 153, in order to provide the visual effect that acorresponding image is seen in 3D, the 3D modice 183 may apply imageprocessing (for example, shift) for 3D effect to the corresponding imageto display it in the transparent display area 153. The 3D modice 183 mayshift a screen outputted to the first display 151 to display it in thetransparent display area 153. The 3D modice 183 may adjust theresolution of a screen outputted to the first display 151 or thethickness or brightness of a border to display the screen in thetransparent display area 153. The image processing for 3D effect appliedby the 3D modice 183 may include equalization, sharpening, noisereduction, histogram conversion (image quality improvement), facerecognition, high frequency cut-off filtering (blurring), high frequencyenhancement filtering (sharpening), angle conversion, size conversion,saturation conversion, brightness conversion, or template matching inaddition to image shift. Herein, the template matching function may be afunction for processing a specific object in an image to be highlightedwhen an image outputted through the first display 151 and an imageoutputted through the transparent display area 153 overlap partiallywith each other.

According to an embodiment, when at least a portion of an imagedisplayed on the first display 151 is seen through the transparentdisplay area 153, in order to provide the visual effect that acorresponding image is seen in 3D, the depth modice 186 may apply imageprocessing to a corresponding image to generate images to be displayedon a top surface 154 and a bottom surface 155 of the transparent displayarea 153 so as to express the depth of the corresponding image. Thedepth modice 186 may adjust the size, shape, color, brightness,contrast, or border processing of a first image to be displayed throughthe first display 151 according to the display characteristic of thefirst display 151 so as to generate a second image that gives depth tothe first image. According to an embodiment, the second image may be animage obtained by reducing the first image at a certain ratio. The depthmodice 186 performs a control on the second image obtained by applyingimage processing to the first image to be outputted through thetransparent display area 153, so that the second image is expressed tobe seen in 3D to a user by using the first image displayed on the firstdisplay 151.

According to an embodiment, when the transparent display area 153 isconfigured with a multilayer, the depth modice 186 may generate a secondimage and a third image, which are obtained by reducing the first imageat different ratios. For example, the transparent display area 153 of amultilayer structure may include at least a first transparent displaylayer and a second transparent display layer. The first image may beoutputted from the first display 151, and then may pass through thetransparent display area 153 and be seen. Simultaneously, the secondimage may be outputted through the first transparent display layer andthe third image may be outputted through the second transparent displaylayer. The second image and the third image together with the firstimage, as 3D images, may be visually recognized by a user.

According to an embodiment, in order for the perspective recognition ofthe first image, the depth modice 186 may reduce the brightness of ascreen outputted to the first display 151, blur the border of the firstimage, or soften the color. Alternatively, the depth modice 186 maydeepen the color of the second image or process the border more clearly.

According to an embodiment, the image processing for 3D effect appliedby the depth modice 186 may include shift, equalization, sharpening,noise reduction, histogram conversion (image quality improvement), facerecognition, high frequency cut-off filtering (blurring), high frequencyenhancement filtering (sharpening), angle conversion, size conversion,saturation conversion, brightness conversion, or template matching.

According to an embodiment, when it is determined that a user sees anexternal object or place through the transparent display area 153, theaugmented reality processing modice 189 may display additionalinformation 156 relating to an object or place within a user's view inthe transparent display area 153. The augmented reality processingmodice 189 may obtain additional information relating to an object orplace within a user's view based on context information or user's viewor face recognition information obtained using a sensor (for example, arear camera sensor) functionally connected to an electronic device.

According to an embodiment, the augmented reality processing module 189transmits a preview image captured using a rear camera sensor to anexternal server to obtain prediction information relating to an objector place within a user's view or additional information to be displayedin the transparent display area 153, from the external server. Theadditional information may include information on the position andheight of a building, and a store or a restaurant in a building within auser's view. According to an embodiment, in order to reduce internaldata processing of the augmented reality processing modice 189, theaugmented reality processing module 189 may receive information to bedisplayed in the transparent display area 153 from an external serverand may then display the received information as it is in thetransparent display area 153 without additional processing. Through suchreal-time processing, the augmented reality processing modice 189 mayreduce time delay or information distortion, each occurring duringaugmented reality processing.

According to an embodiment, the visibility processing modice 192 mayperform image processing for the visibility improvement of informationdisplayed through the transparent display area 153 and/or informationpassing through the transparent display area 153 to be seen.

The visibility of the same information outputted through the firstdisplay 151 and the transparent display area 153 may vary. In thetransparent display area 153, due to the light transmission, thesharpness of information displayed may be lower compared to an opaquedisplay area. According to an embodiment, although information of thesame color is inputted through the first display 151 and the transparentdisplay area 153, the color displayed through the transparent displayarea 153 may be lighter than the color displayed through the firstdisplay 151. In relation to this, the visibility processing modice 192may perform image processing of various methods on information to bedisplayed through the transparent display area 153 based on thetransparency characteristic of the transparent display area 153.

Additionally, according to whether information displayed on the firstdisplay 151 passes through the transparent display area 153, thevisibility of information displayed on the first display 151 may vary.When the information displayed on the first display 151 passes throughthe transparent display area 253 to be seen, relatively lower sharpnessmay be provided compared to when the information does not pass throughthe transparent display area 153 and is delivered directly. According toan embodiment, in the case that a specific color is displayed on thefirst display 151, when the displayed specific color passes through thetransparent display area 153 to be seen, a user may recognize a colorlighter than the specific color. In relation to this, the visibilityprocessing modice 192 may perform image processing of various methods oninformation to be displayed through the first display 151 based on thetransparency characteristic of the transparent display area 153.

According to an embodiment, the visibility processing modice 192 mayclearly process the border area of an object, such as an image or text,in a screen to be displayed through the first display 151 and/or thetransparent display area 153. The visibility processing modice 192 mayapply sharpness effect to the border area of an object. According to anembodiment, the visibility processing modice 192 may process darker thecolor or color sense of a screen to be displayed through the firstdisplay 151 and/or the transparent display area 153. According toanother embodiment, the visibility processing modice 192 may processrelatively darker color or color sense of a screen to be displayed onthe first display 151 compared to a screen displayed through thetransparent display area 153. According to another embodiment, thealternative is possible.

According to an embodiment, the visibility processing modice 192 maygenerate second information (for example, a second screen) to bedisplayed in the transparent display area 153 by applying a specifiedtransparency adjustment value to first information (for example, a firstscreen) to be displayed on the first display 151. According to anembodiment, the visibility processing modice 192 may generate secondinformation (for example, a second screen) to be displayed in thetransparent display area 153 by applying a specified contrast adjustmentvalue to first information (for example, a first screen) to be displayedon the first display 151. The contrast adjustment value may be a value(for example, statistical or experimental value) set to have thevisibility of more than a certain criterion while the first screenpasses through the transparent display area 153 to be seen.

According to an embodiment, when the transparent display area 153 has amultilayer structure including at least a first transparent displaypanel and a second transparent display panel, the visibility processingmodice 192 may specify at least one of the first transparent displaypanel and the second transparent display panel as a panel outputtingsecond information. Alternatively, the visibility processing modice 192may output the second information to the first transparent display paneland the second transparent display panel at the same time.

According to an embodiment, the visibility processing modice 192 maydetermine the output direction of the second information in thetransparent display area 153. The visibility processing modice 192 maydetermine the output direction of the second information based on therelative position relationship of the first display 151 and the seconddisplay 152. When the first display 151 and the transparent display area153 are disposed to overlap at least partially with each other, thevisibility processing modice 192 may output the second information in ahorizontal direction. Alternatively, when the first display 151 and thetransparent display area 153 are disposed parallel to each other, thevisibility processing modice 192 may output the second information in areverse horizontal direction. Alternatively, the visibility processingmodice 192 may dynamically adjust the output direction of the secondinformation according to an angle between the first display 151 and thesecond display 152.

According to an embodiment, when the resolution of the first display 151and the resolution of the transparent display area 153 are differentfrom each other, the visibility processing modice 192 may adjust thesize of the second information (for example, a second screen) outputtedto the transparent display area 153 to match the size of the firstinformation (for example, a first screen) outputted to the first display151. Additionally, the visibility processing modice 192 may performimage processing on the first information and/or the second informationin order to allow the color, shading, contrast, or saturation of thesecond information (for example, a second screen) outputted to thetransparent display area 153 to be similar to the color, shading,contrast, or saturation of the second information (for example, a firstscreen) outputted to the first display 151.

According to an embodiment, the visibility processing modice 192 maychange the second information being outputted to the transparent displayarea 153 in response to an event recognized by a motion sensor relatingto the second display 152. For example, the visibility processing modice192 may dynamically adjust at least one of the sharpness, luminosity,contrast, or color of the second information (for example, a secondscreen) being outputted to the transparent display area 153 in responseto a bending or hinge operation of the second display 152.Alternatively, the visibility processing modice 192 may dynamicallyadjust the transparency for at least a partial area of the transparentdisplay area 153 in response to a bending or hinge operation of thesecond display 152.

In the above embodiments, although it is disclosed that the seconddisplay control modice 172 includes all the 3D modice 183, the depthmodice 186, the augmented reality processing modice 189, and thevisibility processing modice 192, various embodiments are not limitedthereto. For example, the second display control modice 172 may includeat least one of the 3D modice 183, the depth modice 186, the augmentedreality processing modice 189, and the visibility processing modice 192.Hereinafter, additional information on the electronic device 101 isprovided through the drawings described later.
